[ Impact ]
- * This is a hardware enablement SRU.
+ * This is a hardware enablement SRU.
* In partner engineering, we maintain specific nvidia hardware which require
a dedicated optimized kernel. We need to build Desktop images for these
machines, on a regular basis, to run the certification suites.
Right now the kernel we need is `linux-nvidia-hwe-24.04-edge`, but I'm
anticipating that it will be `linux-nvidia-hwe-24.04` at some point so this
should be possible to configure.
* The resolution involves adding a subarchitecture (SUBARCH) option in
Desktop images which, when provided, will behave accordingly. a CHANNEL
option can also be provided to add the channel.
[ Test Plan ]
1. Create a Desktop ISO. It will contain the generic kernel.
2. Create a Desktop ISO with the proposed package. It will contain the
generic kernel too.
3. Create a Desktop ISO after mentioning subarch=nvidia in the metadatas.
The kernel should now be nvidia's.
4. Create a Desktop ISO after mentioning subarch=nvidia in the metadatas.
The kernel should now be nvidia's edge.
5. Build the images from 3, 4, 5 with ubuntu-cdimage and test that they boot
correctly and have the right kernel.
Please not that the debian-cd branch to be used it the following merge
proposal:

6. Redo all these steps with Live Server image
[ Where problems could occur ]
* If the bash scripts becomes invalid or go in the wrong branch, the
image build process could simply stop working, or provide images with
the wrong kernel. The test plan reflects this risk.
[ Other Info ]
- * The kernel that are made available with this fixed are only released
- on LTS series right now. To test it on non LTS series, we'd have to
- package the kernel into a private PPA before.
+ * The kernel that are made available with this fixed are only released on
LTS series right now. To test it on non LTS series, we'd have to package the
kernel into a private PPA before.
+ * Nevertheless, a MP for plucky was added to fulfill the SRU process in
regard to apply patches from newest to oldest release.
+ * But skipping 'Oracular' since it reaches it's end of live very soon (and
to avoid extra effort, since plucky is a newer non-LTS).
+ * But most relevant is to have the patch in the latest LTS / noble.
